DS90UR124: How to repeat FPD LINK II by DS90UR124 or which TI chipset can repeat FPD LINK II and compatible with DS90UR124

Hi user6391035,

If the UR124 is on the board, the 925 and 926 could be used in repeater mode with fpd iii as the interconnect would be parallel signals.

Hi Bryan, 

Thanks for your answer, but 925 and 926 can only use for FPD LINK II input, UR124 is FPD LINK II, so it is not compatible, right? 

Hi user6391035,

From your original device to the UR124 the link is FPDII.  The UR124 then connect via RGB to the 925 (TX source) as shown in figure 16 of of the 925 datasheet:

From there on FPD-link III could be used in the repeater application.

Hi Bryan,

Thanks for your quick reply. So what you mean is that we need to add extra 925 before the repeater connection (926 and 925), right?

And if we want to use repeater mode for 1:2, we need one 926 as receiver and two 925 as transmitter, right? It seems use a bit too much chipset. I found there is a repeater chip ds25br204, is it compatible with FPD LINK II? If yes, it can use less chipset to repear lvds signal.

Best Regards

Hi, 

What is DS25CP204 device, I can't find any information about it.
